[dpdk-dev] [PATCH v2 3/6] examples/l3fwd-vf: remove example from DPDK

[Ciara Power <ciara.power@intel.com>]

From: Bruce Richardson <bruce.richardson@intel.com>

The main l3fwd app should work with both PF and VF devices, so remove the
VF-only l3fwd example.

-L3 Forwarding in a Virtualization Environment Sample Application
-================================================================
-
-The L3 Forwarding in a Virtualization Environment sample application is a simple example of packet processing using the DPDK.
-The application performs L3 forwarding that takes advantage of Single Root I/O Virtualization (SR-IOV) features
-in a virtualized environment.
-
-Overview
---------
-
-The application demonstrates the use of the hash and LPM libraries in the DPDK to implement packet forwarding.
-The initialization and run-time paths are very similar to those of the :doc:`l3_forward`.
-The forwarding decision is taken based on information read from the input packet.
-
-The lookup method is either hash-based or LPM-based and is selected at compile time.
-When the selected lookup method is hash-based, a hash object is used to emulate the flow classification stage.
-The hash object is used in correlation with the flow table to map each input packet to its flow at runtime.
-
-The hash lookup key is represented by the DiffServ 5-tuple composed of the following fields read from the input packet:
-Source IP Address, Destination IP Address, Protocol, Source Port and Destination Port.
-The ID of the output interface for the input packet is read from the identified flow table entry.
-The set of flows used by the application is statically configured and loaded into the hash at initialization time.
-When the selected lookup method is LPM based, an LPM object is used to emulate the forwarding stage for IPv4 packets.
-The LPM object is used as the routing table to identify the next hop for each input packet at runtime.
-
-The LPM lookup key is represented by the Destination IP Address field read from the input packet.
-The ID of the output interface for the input packet is the next hop returned by the LPM lookup.
-The set of LPM rules used by the application is statically configured and loaded into the LPM object at the initialization time.
-
-.. note::
-
-    Please refer to :ref:`l2_fwd_vf_setup` for virtualized test case setup.
-
-Compiling the Application
--------------------------
-
-To compile the sample application see :doc:`compiling`.
-
-The application is located in the ``l3fwd-vf`` sub-directory.
-
-Running the Application
------------------------
-
-The application has a number of command line options:
-
-.. code-block:: console
-
-    ./build/l3fwd-vf [EAL options] -- -p PORTMASK  --config(port,queue,lcore)[,(port,queue,lcore)] [--no-numa]
-
-where,
-
-*   --p PORTMASK: Hexadecimal bitmask of ports to configure
-
-*   --config (port,queue,lcore)[,(port,queue,lcore]: determines which queues from which ports are mapped to which cores
-
-*   --no-numa: optional, disables numa awareness
-
-For example, consider a dual processor socket platform with 8 physical cores, where cores 0-7 and 16-23 appear on socket 0,
-while cores 8-15 and 24-31 appear on socket 1.
-
-To enable L3 forwarding between two ports, assuming that both ports are in the same socket, using two cores, cores 1 and 2,
-(which are in the same socket too), use the following command:
-
-.. code-block:: console
-
-   ./build/l3fwd-vf -l 1,2 -n 4 -- -p 0x3 --config="(0,0,1),(1,0,2)"
-
-In this command:
-
-*   The -l option enables cores 1 and 2
-
-*   The -p option enables ports 0 and 1
-
-*   The --config option enables one queue on each port and maps each (port,queue) pair to a specific core.
-    The following table shows the mapping in this example:
-
-    +----------+-----------+-----------+------------------------------------+
-    | **Port** | **Queue** | **lcore** | **Description**                    |
-    |          |           |           |                                    |
-    +==========+===========+===========+====================================+
-    | 0        | 0         | 1         | Map queue 0 from port 0 to lcore 1 |
-    |          |           |           |                                    |
-    +----------+-----------+-----------+------------------------------------+
-    | 1        | 0         | 2         | Map queue 0 from port 1 to lcore 2 |
-    |          |           |           |                                    |
-    +----------+-----------+-----------+------------------------------------+
-
-Refer to the *DPDK Getting Started Guide* for general information on running applications
-and the Environment Abstraction Layer (EAL) options.
-
-Explanation
------------
-
-The operation of this application is similar to that of the basic L3 Forwarding Sample Application.
-See :ref:`l3_fwd_explanation` for more information.
